Well thats a big part of what the legal system does. Some lawyers argue that the line should be over here, then others argue that the line should be over there. Many of these arguements a based on prior court decisions. Decisions are argued further in appelate courts and all the way up to supreme courts. Where the line is drawn is up for debate, then its decided in courts, and them a new case comes along and its of for debate again.

Where does it become an attempt, when he leaves his home? When he gets in the CVS parking lot? When he walks through the door? Its debatable. I could look up rulings on similar cases, but I won't.

My point is that the prosecuters have a case. The courts might rule that it wasn't an attempt (in today's law enforcement driven society, i doubt it). But the prosecuters certainly have a reasonable case.
